Did you also change the motherboard, not only CPU? If yes, ask in the Gigabyte Z77 motherboard thread. The tertiary memory timings might be set more aggressive than on other boards by default, and XMP profiles only set primary and secondary memory timings. Also, newer UEFI versions introduced a mysterious "slew rate" setting for the memory on Z77X-UD3H. There was something about problems overclocking Samsung memory and that setting can fix that. You might want to play around with it and flash newer UEFI if you don't have it.
